Diesel Exhaust Brakes

An Exhaust Brake System is a supplementary braking system used to help slow your vehicle. This slowing power is achieved by restricting the flow of exhaust gases and increasing back pressure inside the engine. This increased back pressure creates resistance against the pistons in your engine, slowing the crankshaft's rotation and ultimately helping to slow your vehicle.

Unlike gasoline engines, diesel engines produce no vacuum when you release the throttle to help slow the vehicle. The higher compression of the diesel acts like a spring on the crankshaft, even with no fueling. An exhaust brake restricts the exhaust, making the pistons work harder, slowing the crankshaft and the truck. Read more »
